The decision by Serbia’s state-owned power utility, EPS, to engage foreign joint-venture partners for the development of solar and battery storage projects on its coal ash landfills marks a significant shift in the country’s energy strategy. This move contrasts with trends observed in other European nations, where state utilities have typically leveraged their assets to develop renewable projects independently. The underlying motivations for EPS’s approach are complex, involving financial, regulatory, and operational considerations.
EPS’s coal landfills and overburden dumps represent not only potential renewable energy sites but also considerable liabilities. These areas come with environmental remediation obligations that are politically sensitive and uncertain in terms of long-term financial impact. By partnering with foreign entities, EPS can externalize some of these risks while retaining nominal ownership of the land. This joint-venture structure effectively acts as a risk firewall, allowing EPS to manage its legacy liabilities more effectively.
Financial constraints further complicate EPS’s ability to invest in large-scale renewable projects. The utility is already burdened with significant capital expenditures related to maintaining lignite operations and modernizing existing infrastructure. Developing a utility-scale solar and battery project could require investments ranging from €180 million to over €1 billion across multiple sites. Given these financial pressures, EPS must prioritize immediate cash flow stability over long-term investments in merchant-exposed solar and storage facilities.
Foreign partners bring crucial advantages that EPS lacks, including access to de-risked capital and regulatory influence. Many of these partners are integrated into European policy frameworks and possess the ability to shape market rules. This partnership increases the likelihood that projects will benefit from favorable treatment under evolving EU-aligned regulations, which is particularly important for EPS as Serbia navigates its non-member status within the EU.
The current market design in Serbia presents additional challenges for EPS. The absence of a fully developed capacity or flexibility market means that solar revenues are largely reliant on merchant conditions, while battery storage profitability hinges on ancillary services and price volatility. By collaborating with foreign partners, EPS can structure projects under long-term power purchase agreements that mitigate exposure to these uncertainties—arrangements that would be difficult for a regulated public utility like EPS to pursue independently.
Governance issues also play a critical role in this decision-making process. EPS operates under intense public scrutiny, making any investment involving foreign technologies politically sensitive. Joint ventures dilute accountability, framing decisions as collaborative outcomes rather than unilateral commitments from EPS. This diffusion of responsibility is particularly advantageous in Serbia’s political climate, where management faces scrutiny over performance and investment choices.
Strategically, the repurposing of coal landfills into solar and battery facilities sends a strong signal regarding Serbia’s commitment to decarbonization. Partnering with foreign entities enhances this narrative by framing the projects within the broader context of the European energy transition ecosystem, which may improve EPS’s reputation among lenders and rating agencies as future financing increasingly depends on environmental, social, and governance (ESG) considerations.
EPS’s choice not to follow the path of other utilities that have successfully developed renewable projects independently stems from its unique institutional constraints. Unlike its peers, EPS does not enjoy explicit state guarantees for transition investments or clear regulatory frameworks that support long-term infrastructure investment. Instead, it operates in a hybrid environment where it is expected to be commercially viable yet remains subject to public accountability.
This strategic decision has implications for market dynamics in Serbia. By allowing foreign partners to take the lead in developing renewable assets on its own land, EPS risks ceding control over emerging flexibility markets. Battery operators involved in these joint ventures may significantly influence market pricing and operational logic, positioning EPS as a buyer rather than an owner of critical energy resources.
Ultimately, EPS’s decision reflects an institutional compromise shaped by current realities within Serbia’s energy landscape. Until there is a clear mandate from the government that supports EPS as a long-term owner of transition assets—complete with regulatory protections and cost recovery mechanisms—foreign joint ventures will likely continue to dominate the development of solar and battery projects on coal landfills in Serbia.
